View details for SuperVORP

As listed on a player's PECOTA card, SuperVORP is VORP with additional adjustments for the following:
1) League difficulty. Players in a more difficult league (e.g. the American League) receive a boost in their SuperVORP to reflect their work against tougher competition.
2) Defensive support (for pitchers). A pitcher's BABIP, and therefore his VORP, are affected by his defense. SuperVORP adjusts the pitcher's VORP by assuming he has a league average defense behind him.
3) Fielding runs above average (FRAA) (for position players). The number of runs a player saves or subtracts with his glove, relative to league average, is added to his SuperVORP score.
SuperVORP can be thought of as analogous to WARP, but with a higher threshold for replacement level.
